STATIONARY EMERGENCY
GENERATOR INSTALLATION
~
k..
Connecting this generator to an electrical
illsystem normally supplied by an electric util-
ity shall be by means of a transfer switch
(such as the "GTS" type transfer switch),
so as to isolate the electric system from the
utility distribution system when the genera-
tor is operating. Failure to isolate the electric
system by these means will result in damage
to the generator and may also result in injury
or death to utility workers due to backfeed of
electrical energy.
ACAUTIONI
t
If an open bottom is used, the engine-gener-
Lmator is to be installed over non-combustible
materials and should be located such that
combustible materials are not capable of
accumulating under the generator set.
Only qualified, competent installation contractors or electricians
thoroughly familiar with applicable codes, standards and regula-
tions should install this stationary emergency electric power sys-
tem. The installation must comply strictly with all codes, standards
and regulations pertaining to the installation.
This genset must be installed on a level surface. The base frame
must be level within two (2) inches all around.
ACAUTIONI
A
After the system has been installed, do noth-
..... ing that might render the installation in non·
compliance with such codes, standards and
regulations.

emergency system, order Engine-Generator Stationary emer-

BASIC STATIONARY EMERGENCY
ELECTRIC SYSTEM
Figure 2.1 shows a schematic diagram of a basic stationary
emergency electric system. Both the UTILITY power supply and
the STANDBY (GENERATOR) output are connected to an approved
transfer switch. The transfer switch is required by electrical code
and serves the following functions:
o
Permits the LOAD circuits to be connected to only one power
supply at a time.
o
Prevents electrical backfeed between the generator and the
UTILITY power circuits.
Notice that both the STANDBY and the UTILITY power supplies to
the transfer switch are protected against overload by a main line
circuit breaker.
